A Review of Literature on the Relative Efficiency of the Dominant and the Nondominant Eye

Evidence on the incidence of ocular dominance is summarized and the findings relevant to the comparative efficiency of the dominant and the non-dominant eye in various perceptual-motor skills and visual functions are reviewed. Although a small advantage for the dominant eye in cases of unmixed manua1-ocular laterality is indicated by some studies, there is reason to doubt the permanence and univereality of this superiority. No advantage for either eye is found in cases of mixed laterality for any function.
